Max "Vision" Butler—currently in a federal penitentiary—once sat atop a billion-dollar criminal empire trafficking in stolen credit-card numbers. How he got there and how the authorities finally managed to topple him is a harrowing tale shot through with technology and tragedy.

Butler was a just another American outcast working in Boise, Idaho in the late 1980s when the Internet began to take off. An incredibly gifted computer geek, he caught the gathering cyber wave—and could have ridden it all the way to untold riches. All he had to do was play it straight and use his incredible programming prowess for good instead of evil. Alas, that's something Butler found harder to do than cracking computer codes. He tried for a while, even becoming a "white hat" cyber-security consultant, but something about the black-market world of online thievery always called him back. In this complex story full of multifaceted machinations both mortal and machine, Wired editor Poulsen successfully sifts through Butler's many sordid capers. While the author avoids alienating readers who don't know their bits from their bytes, he also provides enough jargon for technophiles. Even though readers may not exonerate Butler for swindling so many for so long, Poulsen makes them care enough about him to wonder why he kept doing it.

A compelling ride.

In a previous life, Poulsen served five years in prison for hacking. So the Wired senior editor and "Threat Level" blogger knows intimately the terrain he explores in this page-turning tale of the criminal exploits of a hacker of breathtaking ambition, Max Butler, who stole access to 1.8 million credit card accounts. Poulsen understands both the hows of hacking, which he explains clearly, as well as the whys, which include, but also can transcend, mere profit. Accordingly, his understanding of the hacking culture, and his extensive interviews with Butler, translates into a fascinating depiction of a cybercriminal underworld frightening in its complexity and its potential for harm, and a society shockingly vulnerable to cybercrime. The personalities, feuds, double dealing, and scams of the hackers are just one half of this lively story. The other half, told with equal verve, is law enforcement's efforts to find and convict Butler and his accomplices. (Butler is now serving a 13-year sentence and owes .5 million in restitution.) Poulsen renders the hacker world with such virtual reality that readers will have difficulty logging off until the very end. (Feb.)
